Help with wiring colors on old headphones

"legg"

I've been making my own for years, out of open-cell foam -- it comes for free as packaging in all sorts of product boxes.

Sounds right.

No. Don't mess around with "PVC T-coupling" or any other such nonesense, just put the headphones on and listen. The effect of having them out-of-phase is immediate and obvious. And as Phil said that is s far more reliable method of ensuring correct phasing than assuming that the lead colour use is consistent.

But those who have owned or mucked about with * electrostatic * or * electret * head phones might well be aware of how it sounds - as there are four wires to deal with and every chance that at some stage miss-connection to the amp's speaker terminals will create the issue.

Damn shame these products have all but disappeared or become extraordinarily expensive.

As a reference for sound quality ( or to hear exactly what is on a recording) a pair of Stax Electrostatics were in a class of their own.

That's why we really should have binaural recordings for headphone playback. Weren't there stereo-to-pseudo-binaural converters at one point?

Any tips how? I once bought a Pelican case to hold something disassembled, and I had a heck of a time cutting cavities in the foam provided to fit the pieces. Cutting foam into cylinders would be hard enough -- making them so they can slip over the earpieces seems nightmarish to me.

Dolby Labs bought them ( circa 2003) and everything went pear shaped.

Well these leads plug into the ear sockets with little plugs, assuming they are wired the sam, it should be a simple continuity job.

Most of those phones came with silly din plugs on the end as I recall.

It really does not matter how you do it of course as long as the transducers are in phase at the end with two leads to earth of the plug.

While on the subject of these open back phones. I have a set of 414s and need new ear cushions for them. anyone know if they can still be bought?

If the "lunatic jerk" you're referring to is yourself... I'd say everyone in this group.

The 414s originally came with DIN speaker plugs, but they changed to jacks quite some time ago.>

Well yes, that's what this thread has been about!

I recently bought new muffs for a pair of 414s from Canford.

A pair of headphones with incorrect phasing is about as obvious as being hit on the head with a brick. Amplifier to mono and try listening to something. If you have it right the sound source will appear to be very close to the middle of your head and if not it will be in different places or spread out depending on the frequency.

If you can't tell the difference you don't deserve a hifi system.

You could always look at the cables at the transducer end.

They were standard issue (for some things) in the BBC when I worked there many many years ago

I still quite like them for where an open backed design is suitable.

Phil tends to be rude to everyone. And everything to him is black and white. But I do know out of phase headphones ain't as obvious to all as he suggests, or are to him.

DIN plugs with a socket on the back so they could be inserted 'in line' with other pairs. And a 1/4" stereo jack plug Y adaptor.

As many others here, with far more insight than a jerk like you, have agreed.

Highly unlikey with AKG. On this design, the leads plug into the transducers. One reason they were so popular for pro use - they unplug rather than break if strained.

"Dave Plowman (Nutcase )

Only ONE ear unit is involved.
